A few notes on how the video above relates to Mr. Vizza's class.
At 2:20 seconds, He says "these numbers work".
In our class we say that these numbers "make the statement true" or "are part of solution set."
At 1:05 he sets up his number line In terms of his "1 more and 1 less" method of graphing
I tend to graph a little differently in class. I only use the zero and the number in the problem calling it the "critical number." The answers are the same but I draw them just a little differently. Compare the graphs here.
